What is Flashcard AI?

Flashcard AI is a three-part ecosystem:
  • Desktop app (.NET 8 / WPF) — The primary control center for Windows. Scan image folders, manage decks, study, quiz, and sync to the cloud.
  • Desktop app (Python) — A legacy Python/CustomTkinter version with the same scanning and deck management features.
  • Mobile app (Android) — A React Native companion app for studying and quizzing on your phone with gesture controls.
All three clients share the same decks.json data format and sync through Google Drive AppData.

​
How it works

1

Scan your materials

Point the desktop app at a folder of images (lecture slides, book pages, exam screenshots) or a video file. Flashcard AI batches them into PDFs and sends them to Google Gemini for extraction.
2

Review your deck

Gemini returns structured flashcards with questions, answer options, and correct answers. Cards flagged as AI-inferred are marked so you can review them.
3

Study and quiz

Use Study Mode to flip cards and self-score, or Quiz Mode to practice with single and multiple-choice questions. Sessions are automatically saved so you can pick up where you left off.
4

Sync and export

Sync your decks to Google Drive so they’re available on all your devices. Export to Quizlet-compatible .txt files to share or import into other study tools.
